java.lang.Object org.joda.primitives.iterator.impl.ArrayDoubleIterator
public class ArrayDoubleIterator
An iterator over an array of double
values.
This class implements Iterator
allowing
seamless integration with other APIs.
The iterator can be reset to the start if required.
It is unmodifiable and remove()
is unsupported.

public ArrayDoubleIterator(double[] array)
double
values.
The array is assigned internally, thus the caller holds a reference to the internal state of the returned iterator. It is not recommended to modify the state of the array after construction.
array
- the array to iterate over, must not be null
IllegalArgumentException
- if the array is nullMethod Detail |

public static ArrayDoubleIterator copyOf(double[] array)
double
values.
The specified array is copied, making this class effectively immutable.
Note that the class is not final
thus it is not truly immutable.
